.10 all whom it may concern.-

Be it known that 1, PETER BLATT, a citi- Zen of the United States ofAmerica, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inDumping; Wagons, of which the following is a specifica tion, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in dumpingwagons, and has for its object the provision of novel means formanipulating the hinged doors or gates of the wagon.

Another object of this invention is to provide novel means in connectionwith an operating-lever for locking the gates or doors in a closedposition.

The invention aims to dispense with the numerous chains and mechanismgenerally used in connection with this type of .wagon for closing andopening the dumping doors or gates of a wagon.

The wagon as constructed by me is eX- tremely-simple in construction,strong and durable, and comparatively inexpensive to manufacture.

WVith the above and other objects in view the invention finally consistsin the novel construction, combination, and arrangement of parts, whichwill be hereinafter more fully described and then specifically pointedout in the claims, and referring to the drawings accompanying thisapplication, like numerals of reference designate corresponding partsthroughout the several views, in which Y Figure 1 is a side elevation ofa wagon constructed in accordance with my invention. Fig. 2 is a bottomplan view thereof. Fig. 3 is an end view of my improved wagon,illustrating the operating mechanism thereof. Fig. 4 is a view of theopposite end of my improved wagon, and Fig. 5 is an enlarged detailelevation view of the operating mechanism. p

To put my invention into practice, I employ a wagon consisting ofside-boards 1 1 and end-boards 2 2, all of which gradually taper andform the body portion or hopper of my improved wagon. To the sides 1 1of the wagon and at the lower edges thereof are hinged doors or gates 3and 3, hinges 4 of a conventional form being employed in thisconnection. The confronting edge of one of the doors is provided with acleat 5, which is adapted to overlie the adjoining door when in a closedposition. The ends of the door 3 near its confronting edge are providedwith brackets 6 6, in which are journaled pulleys 7 and 8, that servefunctionally as sheaves. The door 3 is also provided with similarpulleys 9 and 10, journaled in brackets 11 11.

My invention resides in the novel means I employ for manipulating thedoors or gates 3 and 3, and I have aimed to locate the oper atingmechanism of my improved wagon conveniently near to the driver of thewagon.

Upon the end-board 2 I secure brackets 12' 12, between which isjournaled a shaft 14. To the shaft is attached a cable or chain, asindicated at 15, and said cable is adapted to pass down around thepulley 7, along the confronting edge of the door 2, and over the pulley8, from where it passes upwardly over a pulley 16, journaled in abracket 17, carried by the end-board 2. The cable then passes downwardlyover the pulley 10, alon the confronting edge of the door 3, over pulley9, upwardly to the shaft 14, where it is secured, as

indicated at 16, forming an endless elevating-cable.

To retain the doors or gates 3 and 3 in a closed position and to elevatethem at any tially Vshaped pawl 23. This pawl is normally held inengagement with the ratchetwheel 18 by gravity and is elevated by abeveled lug 24, carried by the operating-lever 19, which is adapted toengage the angular arm 25 of the pawl 23 when said operating-lever ismoved rearwardly. The doors or gates 3 and 3 are normally held in aclosed position by the pawls 20 and 23, and when it is desired torelease the same the operating-lever 19 is moved rearwardly, saidmovement causing the lug 24 to engage the arm 25 of the pawl 23 andslightly elevate the same without at this time disengaging the pawl 23from the ratchet. The engagement of the lug 24 with the arm 25 causessaid arm to strike the pawl 20, and said pawl 20 will be elevated,releasing the ratchet-wheel 18. The further rearward movement of thelever 19 will bring the and the weight of the load within the wagoncauses the doors 3 and 3 to open and the'ca ble to unwind upon the shaft14.

From the foregoing description it will be observed that the firstportion of the rear ward movement of the lever19has the effect ofcausing the arm to release/the pawl 20 from engagement with theratchet-wheellS, and the further movement of thelever 19'has the effectof disengaging the pawl 23 from the ratchet-wheel 18. The successivereleasing of the pawis 20 and 23 from engagement .with the ratchet-wheel18 in the order ,abovedescribed is of particular importance, for-if thepawl 23 was first released the entire weight of the loadibeing imposedupon theshaft 14 and the ratchetwheel 18 would cause the lever 19 to bethrown rearwardly with reat violence, and this movement would, i theoperator maintained his hold of the lever, possibly inflict seriousinjury uponhim or, if-he released his hold of the lever, would impose aserious strain upon the lever and upon the pawl 20.

It will of course be understood that the ratchet-wheel 18 is fixed uponthe shaft 14 and that the operating-lever '19 is loosely mountedthereon. By this construction I am enabled to close the doors 3 and 3by, a plurality of oscillating movements exerted through the medium ofthe lever 19. The manner of arranging the cable and the pulleys upon thedoors 3 and 3 permits of both doors being raised and loweredsimultaneously and easily manipulated by the driver of the wagon.

While I have herein described the preferred manner of arranging theoperating mechanism of my im roved wagon, I do not care to confinemyself to the exact construction shown, as various structural changesmay-be made without departing from the general spirit and scope of-theinvention.

What I claim, and desire to secure by Letters Patent, is

1. In a dumping-Wagon, the combination with a hopper provided withhinged doors, of a shaft rotatably mounted in bearings upon one end ofsaid hopper, means secured to said shaft and supported by an elementmounted.

upon an opposite end of the hopper for normally maintaining said doorsin their closed position and means for normally locking said shaftagainst rotation, said last-named means embodying a ratchet rigidlymounted upon said shaft, a lever loosely mounted upon said shaft and apair of coacting pawls, normally in engagement with the teeth of saidratchet, one of said pawls being carried by said lever and-the otherbeing journaled in abearing mounted upon the end of the hopper, saidlast-named pawl being provided with ,an armadapted to engage saidfirstnamedipaw-land said lever being provided with means for engagingthe pawl on the hopper,-said parts being so constructed and arrangedthat when'the lever is moved rearwardly the pawl on the lever will bedisengaged fromthe ratchet-wheel and the pawl on the hopper will besubsequently disengaged from the ratchet-wheelas and for the purposedescribed.

2. In a dumping-wagon, the combination with a hopper provided withhinged doors, of a shaft journaled in bearings upon one end of saidhopper, a chain having its ends secured to said shaft and movablysupported from said hopper, said chain being disposed in a positionrelative to said doors, whereby to normally maintain the same closed, aratchet rigidly mounted upon said shaft, a lever loosely mounted uponsaid shaft adjacent said ratchet, a counterweighted pawlloosely mountedupon said lever andadapted to engage the teeth of the ratchet to rotatethe same upon movement of the lever, an L- shaped pawl mounted in abearing upon the end of the hopper adjacent to said lever, said pawltbeing in normal engagement with the .teethof the ratchet to prevent thebackward movement ofthe shaft under the weight of the doors .and theload supported thereby,

an -extension carried by said lever and adapted, upon the movementthereof, to engage one-arm of said ;Lshaped pawl to release the latterfrom engagement with the teeth of the ratchet.

In testimony whereof I afIiX my signature in the presence of twoWitnesses.
